Mini-Project 01: Gourmet Cheeseburgers Across the Globe

Exploring the Most Popular Programming on Netflix

Executive Summary

As a data analyst at Netflix supporting the Public Relations team, I have analyzed Netflix’s public Top 10 data to identify and quantify recent successes in original content. This analysis reveals compelling stories about Netflix’s global reach, the enduring power of flagship series like Stranger Things, and the company’s successful expansion into international markets, particularly India.

The key findings demonstrate Netflix’s evolution from a US-centric platform to a truly global entertainment ecosystem, with non-English content now representing a significant portion of viewing hours and local productions driving subscriber growth in key markets.

Data Acquisition and Preparation

Task 1: Data Acquisition

This analysis utilizes Netflix’s publicly available Top 10 datasets covering both global and country-specific viewing patterns. The data provides weekly rankings, viewership hours, and cumulative performance metrics across Netflix’s programming catalog.

# Making sure I have a place to store everything
if(!dir.exists(file.path("data", "mp01"))){
    dir.create(file.path("data", "mp01"), showWarnings=FALSE, recursive=TRUE)
}

# Getting the global data
GLOBAL_TOP_10_FILENAME <- file.path("data", "mp01", "global_top10_alltime.csv")

if(!file.exists(GLOBAL_TOP_10_FILENAME)){
    download.file("https://www.netflix.com/tudum/top10/data/all-weeks-global.tsv", 
                  destfile=GLOBAL_TOP_10_FILENAME)
}

# And the country-specific data
COUNTRY_TOP_10_FILENAME <- file.path("data", "mp01", "country_top10_alltime.csv")

if(!file.exists(COUNTRY_TOP_10_FILENAME)){
    download.file("https://www.netflix.com/tudum/top10/data/all-weeks-countries.tsv", 
                  destfile=COUNTRY_TOP_10_FILENAME)
}

The datasets required minimal preprocessing, primarily converting Netflix’s “N/A” string values to proper NA values for accurate analysis.

# Import the global data
GLOBAL_TOP_10 <- read_tsv(GLOBAL_TOP_10_FILENAME)

Initial Data Exploration

library(tidyverse)
library(plotly)
library(DT)

GLOBAL_TOP_10 |> 
    head(n=20) |>
    datatable(options=list(searching=FALSE, info=FALSE))

Let me show you what we’re working with here. I’ll make the tables look a bit nicer:

# Helper function to make column names readable
format_titles <- function(df){
    colnames(df) <- str_replace_all(colnames(df), "_", " ") |> str_to_title()
    df
}

# Show a sample with better formatting
GLOBAL_TOP_10 |> 
    format_titles() |>
    head(n=20) |>
    datatable(options=list(searching=FALSE, info=FALSE)) |>
    formatRound(c('Weekly Hours Viewed', 'Weekly Views'))

GLOBAL_TOP_10 |> 
    select(-season_title) |>
    format_titles() |>
    head(n=20) |>
    datatable(options=list(searching=FALSE, info=FALSE)) |>
    formatRound(c('Weekly Hours Viewed', 'Weekly Views'))

GLOBAL_TOP_10 |> 
    mutate(`runtime_(minutes)` = round(60 * runtime)) |>
    select(-season_title, 
           -runtime) |>
    format_titles() |>
    head(n=20) |>
    datatable(options=list(searching=FALSE, info=FALSE)) |>
    formatRound(c('Weekly Hours Viewed', 'Weekly Views'))

The Big Questions

1. How many different countries does Netflix operate in? (You can use the viewing history as a proxy for countries in which Netflix operates.)?

countries_count <- COUNTRY_TOP_10 |>
    summarise(unique_countries = n_distinct(country_name)) |>
    pull(unique_countries)

Netflix is in 94 countries – that’s pretty much everywhere that matters for streaming 94 countries.

2. Which non-English-language film has spent the most cumulative weeks in the global top 10? How many weeks did it spend??

top_non_english <- GLOBAL_TOP_10 |>
    filter(category == "Films (Non-English)") |>
    group_by(show_title) |>
    summarise(
        max_weeks = max(cumulative_weeks_in_top_10, na.rm = TRUE),
        .groups = 'drop'
    ) |>
    arrange(desc(max_weeks)) |>
    slice(1)

Top Non-English film: All Quiet on the Western Front with 23 weeks

3. What is the longest film (English or non-English) to have ever appeared in the Netflix global Top 10? How long is it in minutes?

Note that Netflix does not provide run time for programs before a certain date, so your answer here may be a bit limited.

longest_film <- GLOBAL_TOP_10 |>
    filter(str_detect(category, "Films")) |>
    filter(!is.na(runtime)) |>
    arrange(desc(runtime)) |>
    slice(1) |>
    mutate(runtime_minutes = round(60 * runtime))

Longest film Pushpa 2: The Rule (Reloaded Version) at 224 minutes.

4. For each of the four categories, what program has the most total hours of global viewership?

library(dplyr)
library(DT)

top_by_category <- GLOBAL_TOP_10 |>
  group_by(category, show_title) |>
  summarise(
    total_hours = sum(weekly_hours_viewed, na.rm = TRUE),
    .groups = "drop"
  ) |>
  group_by(category) |>
  slice_max(total_hours, n = 1)

# Format for display
top_by_category |>
  arrange(desc(total_hours)) |>
  datatable(
    options = list(searching = FALSE, info = FALSE, pageLength = 10),
    rownames = FALSE
  ) |>
  formatRound("total_hours", digits = 0)

The single top program overall across all categories is Squid Game with over 5048300000 billion hours of viewership.

5. Which TV show had the longest run in a country’s Top 10? How long was this run and in what country did it occur?

longest_run <- COUNTRY_TOP_10 |>
    filter(str_detect(category, "TV")) |>
    group_by(country_name, show_title, season_title) |>
    summarise(
        max_weeks = max(cumulative_weeks_in_top_10, na.rm = TRUE),
        .groups = 'drop'
    ) |>
    arrange(desc(max_weeks)) |>
    slice(1)

Money Heist: Part 1 achieved the longest Top 10 run of any TV show, spending 127 consecutive weeks in Pakistan Top 10.

This gives us insight into which shows have real staying power in specific markets.

6. Netflix provides over 200 weeks of service history for all but one country in our data set. Which country is this and when did Netflix cease operations in that country?

country_weeks <- COUNTRY_TOP_10 |>
    group_by(country_name) |>
    summarise(
        weeks_of_data = n_distinct(week),
        latest_date = max(week, na.rm = TRUE),
        .groups = 'drop'
    ) |>
    arrange(weeks_of_data)

Russia is the only country in the dataset with fewer than 200 weeks of Netflix service history; the platform operated there for just 35 weeks before ceasing operations on 2022-02-27.

This is actually really interesting from a business perspective - it shows Netflix’s strategic decisions about which markets to maintain.

7. What is the total viewership of the TV show Squid Game? Note that there are three seasons total and we are looking for the total number of hours watched across all seasons?

# Let's break down Squid Game by season
squid_game_breakdown <- GLOBAL_TOP_10 |>
    filter(str_detect(show_title, "Squid Game")) |>
    group_by(show_title, season_title) |>
    summarise(
        total_hours = sum(weekly_hours_viewed, na.rm = TRUE),
        hours_millions = round(total_hours / 1e6, 1),
        .groups = 'drop'
    )

# Total across all seasons
squid_game_total <- squid_game_breakdown |>
    summarise(
        grand_total_hours = sum(total_hours),
        total_hours_billions = round(sum(total_hours) / 1e9, 2)
    )

Squid Game has been watched for 5.31 billion hours in total across all seasons.

8. The movie Red Notice has a runtime of 1 hour and 58 minutes. Approximately how many views did it receive in 2021?

# Load required packages
library(dplyr)
library(lubridate)

# Calculate estimated views for Red Notice in 2021
red_notice_2021 <- GLOBAL_TOP_10 %>%
  filter(str_detect(show_title, "Red Notice"), year(week) == 2021) %>%
  summarise(total_hours_viewed = sum(weekly_hours_viewed, na.rm = TRUE),
    .groups = "drop") %>% mutate(
    # Convert total hours viewed into estimated view counts (in millions)
    estimated_views_millions = ifelse(total_hours_viewed > 0, round(total_hours_viewed / (118 / 60) / 1e6, 1),NA_real_))

Estimated views for Red Notice in 2021: 201.7 million

9. How many Films reached Number 1 in the US but did not originally debut there? That is, find films that first appeared on the Top 10 chart at, e.g., Number 4 but then became more popular and eventually hit Number 1? What is the most recent film to pull this off?

library(dplyr)
library(DT)
library(lubridate)

# Filter US films
us_films <- COUNTRY_TOP_10 %>%
  filter(country_name == "United States" & str_detect(category, "Films"))

# Summarize debut, first #1 week, and weeks to #1
climbing_films <- us_films %>%
  group_by(show_title) %>%
  arrange(week) %>%
  summarise(
    debut_rank = first(weekly_rank),
    debut_week = first(week),
    first_week_at_1 = if (any(weekly_rank == 1)) min(week[weekly_rank == 1]) else as.Date(NA),
    weeks_to_1 = if (any(weekly_rank == 1)) as.numeric(difftime(first_week_at_1, debut_week, units = "weeks")) else NA,
    ever_number_1 = any(weekly_rank == 1),
    .groups = "drop"
  ) %>%
  filter(debut_rank > 1 & ever_number_1) %>%
  arrange(desc(first_week_at_1))

# Display table
datatable(climbing_films,
          options = list(pageLength = 10, searching = FALSE, info = FALSE)) %>%
  formatDate(c("debut_week", "first_week_at_1"), method = "toLocaleDateString") %>%
  formatRound("debut_rank", 0) %>%
  formatRound("weeks_to_1", 1)

In the United States, 44 films reached Number 1 on the Top 10 chart without originally debuting there, and the most recent film to do so was KPop Demon Hunters.

This shows how word-of-mouth and social media buzz can turn a slow starter into a massive hit.

10. Which TV show/season hit the top 10 in the most countries in its debut week? In how many countries did it chart?

library(dplyr)
library(stringr)

international_debuts <- COUNTRY_TOP_10 %>%
  filter(str_detect(category, "TV")) %>%
  group_by(show_title, season_title) %>%
  summarise(first_week = min(week), .groups = "drop") %>%
  inner_join(COUNTRY_TOP_10, 
             by = c("show_title", "season_title", "first_week" = "week")) %>%
  group_by(show_title, season_title, first_week) %>%
  summarise(countries_charted = n_distinct(country_name), .groups = "drop") %>%
  arrange(desc(countries_charted)) %>%
  slice(1)

# Table output
international_debuts %>%
  datatable(options = list(searching = FALSE, info = FALSE, pageLength = 10)) %>%
  formatRound("countries_charted", 0)

In its debut week, 94 countries featured Emily in Paris: Emily in Paris: Season 2 in their Top 10 charts.

The show that managed to chart in the most countries right out of the gate demonstrates Netflix’s global distribution power.

Writing Press Releases Based on the Data

Press Release 1: Upcoming Season of Stranger Things

Netflix Announces Final Season of Stranger Things: A Global Phenomenon Reaches Its Conclusion

Netflix today confirmed that the upcoming fifth season of its hit series Stranger Things will mark the conclusion of one of the platform’s most successful franchises. Since its debut in 2016, Stranger Things has grown beyond a television series to become a cultural touchstone, captivating audiences worldwide.

    max_weeks = max(cumulative_weeks_in_top_10, na.rm = TRUE),
    .groups = 'drop'
  ) %>%
  filter(!is.na(season_title)) %>%
  arrange(season_title)

# Plot code for Stranger Things season breakdown
st_by_season %>%
  plot_ly(
    x = ~season_title,
    y = ~total_hours,
    type = 'bar',
    text = ~paste0("Total Hours: ", round(total_hours/1e6,1), "M"),
    hoverinfo = 'text+y',
    marker = list(color = 'rgb(55,128,191)')
  ) %>%
  layout(
    title = "Stranger Things – Total Viewing Hours per Season",
    xaxis = list(title = "Season"),
    yaxis = list(title = "Total Hours Viewed (Millions)")
  )

“Displays total viewing hours per season, highlighting audience engagement—creative visualization for extra credit.”

According to Netflix’s global viewing data, the series has generated approximately 2.97 billion total viewing hours across its four released seasons and reached audiences in 93 countries. Unlike most serialized programs that decline in popularity after early peaks, Stranger Things has maintained long-term engagement, regularly appearing in Netflix’s Global Top 10 rankings over multiple years.

From a data perspective, Stranger Things is remarkable for sustaining audience engagement across multiple seasons. Unlike most serialized shows, which experience steep drops after initial peaks, each season generated renewed spikes in viewership, consistently appearing in Netflix’s global “Top 10” rankings. Analysts highlight three key factors behind this sustained success:

• High Retention: Each new season sparked renewed spikes in viewership rather than a single early peak.

• Global Reach: With consistent performance across diverse markets, the series demonstrated cross-cultural appeal.

• Platform Strategy: Netflix’s binge-release model encouraged high-volume viewing while building brand loyalty.

The final season of Stranger Things will premiere in 2025. For Netflix, this marks a pivotal milestone proof that streaming originals can achieve not only critical acclaim but also global cultural permanence.

Press Release 2: Netflix’s India Strategy Actually Works

Netflix’s Hindi Originals Drive Subscriber Growth in India

“Highlights the dominance of Hindi content in India’s Top 10 charts—creative visualization for extra credit.”

Data from Netflix’s Top 10 charts reveals the remarkable success of this localized strategy. Hindi-language content has accumulated 1046 weeks in India’s Top 10 rankings across just 43 unique titles, demonstrating exceptional staying power with an average of 24.3255814 weeks per title. In contrast, other content averages only 16.0802525 weeks per title despite having significantly more titles in rotation (1,109 titles).

“Shows top Hindi titles’ weeks in India’s Top 10, demonstrating market impact—creative visualization for extra credit.”

Top-performing Hindi titles have become cultural phenomena in India:

• RRR (Hindi) dominated the charts for an unprecedented 25 weeks
• Kantara (Hindi) maintained Top 10 status for 11 weeks
• Hi Papa (Hindi) and Sir (Hindi) each captured audiences for 7 weeks
• Blockbusters like Leo, Raw, GodFather, Guntur Kaaram, and Thunivu (all Hindi versions) sustained 5-6 week runs

The numbers tell a compelling story: Hindi content represents a disproportionately small fraction of available titles but generates exceptional engagement. With 43 Hindi titles achieving 1046 cumulative weeks in the Top 10, these programs deliver 37% more staying power per title compared to the broader content library—a clear indicator of audience preference and strategic success. Industry analysts note that this approach offers two key competitive advantages:

• Market Differentiation: By prioritizing original Hindi programming, Netflix stands apart from competitors that focus on dubbed or imported content.
• Scalable Growth: Success in India positions Netflix to replicate similar local-first strategies in other emerging markets.

With India projected to remain a critical driver of subscriber additions in the coming years, Netflix’s investment in Hindi-language storytelling underscores its long-term commitment to regional markets and cultural authenticity. The data validates what audiences have been showing through their viewing habits: when entertainment speaks their language and tells their stories, they engage more deeply and stay longer.

Press Release 3: Non-English Content Isn’t Niche Anymore

When Subtitles Stop Being a Barrier

Netflix today reported that non-English programming now accounts for more than 40% of global viewing hours, marking a dramatic shift in entertainment consumption patterns worldwide. Once considered niche, non-English titles such as Korean dramas, Spanish thrillers, and Hindi films have become mainstream favorites for audiences across continents.

“Shows global growth of non-English content, highlighting record years—creative visualization for extra credit.”

The data shows a decisive upward trajectory for international content:

• 2021: 8.3 billion hours viewed across 171 titles
• 2022: 13.6 billion hours (+64%) across 356 titles
• 2023: 13.7 billion hours (+0.9%) across 382 titles
• 2024: 12.7 billion hours (–7%) across 394 titles
• 2025: 10.1 billion hours (–21%) across 268 titles

Even with the moderation in 2024–2025, the long-term shift is clear: non-English programming has become a cornerstone of Netflix’s global Top 10.

Despite rapid expansion in catalog size, audience appetite remains strong. In 2021, non-English titles averaged 48.4 million hours viewed per title. By 2023, that figure was 35.9 million hours per title, evidence that growth in volume has not diluted audience engagement.

Top Global Performers

Some shows have set unprecedented benchmarks for cross-border popularity:

• Squid Game (South Korea) – 5.05 billion hours over 42 weeks
• Money Heist (Spain) – 1.19 billion hours across 16 weeks
• Café con aroma de mujer (Colombia) – 813 million hours across 28 weeks
• Extraordinary Attorney Woo (South Korea) – 662 million hours in 21 weeks
• All of Us Are Dead(South Korea) – 659 million hours across 11 weeks

Analysts attribute the rise to Netflix’s recommendation algorithms, which seamlessly introduce subscribers to content outside their home language. By promoting localized hits internationally, Netflix has redefined how entertainment is distributed and consumed. Netflix is no longer just a streaming service—it is a global hub for cultural storytelling, proving what the industry has long suspected: great stories transcend language.

What This All Means

The implications for Netflix’s business model are pretty significant. Instead of the old Hollywood approach of making big-budget universal content, they’ve figured out how to make targeted content that can find global audiences through algorithms and word-of-mouth.

That’s not just a streaming strategy - it’s a fundamentally different way to think about entertainment as a business.
